To alla/Pham 'it may concern:

Be it known that I, Fimo It. Kvxkni., a

citizen of the lvnited States. and a resident j of' Edgewood Park, in the county of LXilefollowing is a specification.

My invention relates to vibratory massage apparatus, and it has special reference to such devices as are operated by rotatable Since the driving motor may be located at driving shafts.

The object of my invention is to provide a simple and durable device', of the class above indicated, that shall embody means for varying the kind of motion imparted to the single applicator of the device as well as for adjusting the extent of such motion.

- In/a vibratory massage apparatus it often desirable to )roduce a pulsatingor reciprocating as well as an oscillatory movement and this result has hithertobeen aecomplished by providingr two or more distinct applicators to which different kinds of motions were imparted. lliit'h such devices it is impossible to produce a movement inauy one applicator which is a resultant of a combined oscillatory and pulsating movement.

According to my present invention, l provide a relatively inexpensive device ha ving a single applicator to which either purely oscillatory or purely pulsating movements may be imparted and in which the two movements may be combined in any desired pro` portion by a simple adjustment which may be effected when the device is in' operation. I provide an additional adjustment whereby the variations in the extent of movements produced may be obtained.

Figure 1 of the accompanying drawings is al sectional elevation of a device constructed in accordance with my invention, the

parts being adjusted to produce a purely oscillatory movementof t e applicator and Fig. 2 is an elevation of the device shown in Fig. 1 with the parts adjusted to produce. a substantially pure pulsating.movement.

Referring tothe drawings, the device here illustrated comprises a shaft 1 which may be driven directly or indirectly by any suitable rotary prime mover and-'a driven shaft 2 which is eccentrically and pivotally secured tothe driving shaft 1 and is provided with f an applicator 3 at its outer extremity, a

relatively stationary supporting frame i for the driving shaft and a bearing bracket 5 for the driven shaft which is hinge-connected to the stationary frame 4 so that a rotatable adjustment of one part relative to the other may be elfected. i

As illustrated inthe drawings, thc station ary frame constitutes a stationary member v ot' a propelling motor 6, the arma-ture 7 of which is mounted 011 the driving shaft l.

any convenient point. as above indicated, and may beof any suitable type, I deem it unnecessary to describe the motor in detail. Furthermore, the lnotor illustrated constitutes the subject matter of mv co-pending apthe inner causes the body of the projection t-o slidein a radial groove 12 in the disk. The shaft 2 is supported, intermediate its ends, by a bearing 13 which comprises a sphere -14 through which the shaft projects and a supporting socket 15 therefor which forms' a part of the bracket 5. The device may be supported in the hand of an attendant by means of a. handle 16 which is secured to the bracket 5.

Assuming that the vparts are adjusted as shown in Fig. 1, the applicator 3 is oscillated, the degree of movement being determined by the eccentricity of the projection 9 which may be varied by the adjusting -screw 11. If the bracket 5 is rotated about its hinged connection withthe frame 4, the shaft 2 will be adjusted to produce a considerable angle between the center lines of the two shafts. If this adjustment is continued until the center line of the shaft 2 lies in a plane substantially arallel to that of the disk 8 the movemento the applicator 3 will be pulsating or reci rocating while at intermediate points, the a justment of parts '90 The operation of the device is as follows:

being similar to that shown in Fig. 2, the

movement imparted to the applicator will may be employed for effecting the adjustmentof die projection 9 and, if a constant" movement of pulsation is adequate, the oscillatory movement may be varied by longitudinally adjusting the position ofthe bear..

i110` 13 relative to the shaft 2.

l-ao

l able intermediate bea-ring' for the driven shaft.

raiious structural modifications may be effected within the scope of my present invention and I desire that only such limitations sliall be imposed las are indicated in the `appended claims.

I claim as my invention:

1. In a massage implement, the combination with a driving shaft and a driven shaft having a laterall adjustable pivotal connection to the driving shaft, an intermediate bearing for the driven shaft, and means for adjusting the position of the bearing to vary the angle between the center lines o f the shafts."

2. In a massage implement, the combination with a driving shaft, a laterally adjustable projection operatively connect-ed to one end thereof, and adriven shaft pivotally secured to the projection, of a laterally adjust- 3. In a massage implement, the combination with A,a relatively stationary frame, a driving shaft, a laterally adjustable projection operatively connected to one end of the driving shaft, and a driven shaft pivotally secured to the projection, of a laterally adljustable intermediate bearing for the driven shaft.

4. In av massage implement, the combination with a relatively stationary frame, a driving shaft supported thereby and a driven shafty pivotally connected to the driving shaft, of an intermediate bearing for the driven shaft, v and a supporting bracket for the driven shaftsaid bracket being revolubly adjustable relative to the stationary frame. 4

5. In a massage implement, the combination with a driving shaft, a ball' rojection operatively connected to. one en of said shaft, means forlaterally adjustingl said proj ection, and a driven shaft pivota y secured thereto, of an intermediate bearing, the posif tion of which is laterally adjustable.

6. In a massage implement, the combina-A tion with a drivin shaft, a disk secured thereto and provide with a radially adjustable ball rojection, a driven shaft secured to the bal projection, and a bracket revolubly adjustable relative to the stationary frame and in the plane of the driving shaft, of an Aintermediate bearing for the driven shaft, said bearing being mounted for universal movement 1n the supporting bracket.

In testimony whereof, I have hereunto subscribed my name this 28th day of Dec l FRED lR. KUNKEL.
